This activity set encourages critical thinking and engineering skills through hands-on challenges with adjustable difficulty levels. It introduces STEM concepts like angles, trajectories, and basic physics principles through interactive building exercises. The 13-piece set contains a two-part adjustable catapult, a two-part hoop target, a three-part target funnel, two launch balls, one goal cup, decorative stickers, and an illustrated challenge booklet. The catapult operates without batteries, springs, or rubber bands, relying on manual power. Designed for children aged 5 and older, it provides unplugged learning through trial-and-error experimentation.
